To all whom-fit may concern: I Beit known 'that we, PHiLIPPE A. Dns-Leemans and Lome P. DnsLAURmns, citizensv ofl theilnited States,residing at St. Paul, in the county of Ramsey and State of Minneseta,have invented certain new and useful improvements in Means forConstructing Concrete Columns, of which the following is akspecitcation.

. Our invention relatesto improvements in and consists particularly offan improved holding said mold orf casing'i-n position.

To this end our inventionconslsts in the' features of construction andcombination hereinafter particularly described and claimed.

In the accompanying drawings forming part of this specification, Figurel is an .ele'

vationof our invention; Fig. 2 is a section on line w-m of Fig. l; Fig.3 is a section on line yy of Fig.1; Fig. 4 is a detail of a templetframe; Fig. 5 is a similar View with the templet frame open and shownarranged in" connection with the casing; Fig. 6 is a detail of a blockused in connection with vthe templetframe; Figs.'7 and S'are views ofthe interlocking ends of the'templet frame Fig. 9 is a perspective viewof a door for the casing; Fig. 10 is an elevation of a'modilied form ofour invention for forming square columns; Fig. 11 is'a section onl linee-e of Fig. 10; Fig. 12 isa section on line c-o of Fig. 10; and Fig. 13is a detail of a templet frame used in connection with the modified formof casing shown in Fig. 10.

In the drawings A represents. a mold or casing made of sheet metal.

In order to make the casing expansible tov mold dill'erent sizes ofcolumns we construct it of two adjustably connected plates 2 and 3, theplate Sbeing connected with the plate 2 by means of boltsmft passingthrough the main plate 2 and througlone of a series'of openings .i intheextension plate 3. The

.each templet frame is corposed of two curved arms having hinge cnection 8 and adapted to be connected at their free ends by means of abolt 9 hinged to the end .of one arm 'and adapted to extend through asocketpiece l0 extending outwardly from the end of the other arm, thebolt 9 carryin a nut 1l to bear against theV inner side of t e socketpiece 10. The nut 11 may thus be adjusted to tightl `clamp the frameupon the oasingiV In ordy r to decrease the diameter of the templetframes when the casing is adjusted to its smaller diameter We provide aseries of blocks 12 each block carrying an outwardly and downwardly bentcatch 13 to hook over the templet frame, as indicated in Fig. 1. Thetemplet frame may thus be decreased in size to iit'any size of casing'by vusing blocks 12 of the proper thickness.-

nAs shown in Fig. l' a metal ring 14 is provided for the base of thecolumn and the casing or mold A is supported upon said ring and iscentered by means of arms 15 extending downwardly from the lowermostframe B and interspaced from the'b'ase ring .14- by suitable fillingblocks 16.

The casing A mayconsist of a series. 'of sections sultably securedtogether and connected by bolts 17. Thecasing near its bottoni isprovided with an'opening, closed by a suitable sliding door 18 so thatthe shavings Iand other refuse may be removed before the sameis ill'edwith concrete to form a column, and to allow access to the internal rodsof the column.

In the modified construction shown in Figs. l0 to 13 we show ourinvention adapted for use in thelforming of square columns.y In thislmodification'the casing Aie composed cfa series of plates adjustablyconnected by bolts 1S) passing through openings 2O in the plates, aseries of openings being arranged to allow adjustment ofthe plates.'.lhe plates as shown are bent to form a squarefc'asing and are adaptedto be interlocked -by means of angle irons 2l extending outwardly fromthe free ends of the plates and connected by bolts 22. In thisconstruction the templet frame preferably consists of two right angleshaped. bars 23 adjustably connected together'by bolts 24 extendingthrough openings 25'in the bars, a series of openings being provided teallow adjustment of the bars. Thus filling blocks 12 are not required inthe form shown in Figs. 10 to f13., In this modified form we l haveshown the lowermost templet frame.

'i0 frames and casing will be removed.

bolted to brackets 26' carried by the-base formingmold.

In use the casing will be set up as shown in the drawings, adjusted tothe proper size; and reinforced and held in shape by the tem let frames.The casing will then be fille with the concrete to form the column andwhen'the same has been allowed to stand an indefinite number of times inthe forming of columns. As shown, they may be adj listed to formdifferent sizes of columns.

It will be evident that our invention may be employed for molding ahollow column in lwhich case' the casing A will be turned inside out andthe templets arranged to 't within the casing instead of surrounding it.
